A. 
Division or conveyance of land. No lot or parcel of land, as defined in these regulations, existing on the effective date of these regulations shall be divided, nor shall any easement be granted to any private person, which has the effect of creating a new parcel which will be nonconforming under the provisions of these regulations. Similarly, no lot or parcel shall be decreased in size, by sale, gift, devise, descent or otherwise, so that it or any part of it will be nonconforming under the provisions of these regulations. See Article 9, Nonconforming Lots, Uses, Buildings and Structures.
B. 
Yards and lot coverage. Except as provided for nonconforming uses in Article 9, no land, building, or premises, or part thereof, or other structure shall be constructed, reconstructed, extended, enlarged, moved or altered except in conformity with the regulations herein prescribed for the zone in which it is located. No part of any yard or other open space required about any building may be counted as part of a yard or other space required for any other building.
C. 
Building projections. Nothing in these regulations shall prohibit the projection of not more than three feet into a required yard/setback of pilasters, columns, belt courses, sills, cornices, or other similar architectural features, nor the planting or landscaping of such yards/setbacks.
D. 
Exceptions to height limits. Notwithstanding the height limitations imposed by other provisions of these regulations, church spires, belfries, cupolas, towers, domes, chimneys, flagpoles, radio and television antennas, ventilators, skylights, bulkheads, water tanks and similar features which are accessory to a permitted building, and occupying in the aggregate not more than 10% of the ground area of the building upon which they are located and not used for human occupancy, may be up to 15 feet higher than the highest point of the building upon which they are located. A greater height may be authorized by the Commission as a special permit and may be of such reasonable height as may be necessary to accomplish the purpose they are to serve. Where the structure is the principal structure on the lot, the height limits for the subject zone shall apply, except as provided in § 315-11.13, Wireless telecommunications facilities.
All required front yards shall be measured as the distance specified in the Minimum Front Yard column of Table 8.02, Schedule of Dimensional Requirements, plus the distance specified in Table 8.01 for each street classification, as established for each street in § 315-2.04 of these regulations, unless the required front yard from the street line results in a greater distance.
[Amended 9-16-2025, eff. 10-1-2025]
The requirements of Table 8.02, Schedule of Dimensional Requirements, may be modified in accordance with the following standards, criteria and conditions:
A. 
DI Zone lot frontage. For lots in the Designed Industrial (DI) Zone, the Commission may, as part of a special permit, authorize the reduction of the minimum lot frontage to 50 feet, or may allow access to such lot by a right-of-way 50 feet in width, where the location, grade, and other characteristics of the access are found to be suitable; where the development of such lot does not impede the development of other interior land for industrial development by removing or obstructing the most logical or feasible road access; and where the applicant demonstrates that there are unique characteristics of the size, shape, topography or other physical properties of the lot which make it unusually difficult or unwise to serve it by the required frontage on a public street.
B. 
DI Zone, DNC Zone, DR Zone and DC Zone. In the Designed Industrial, Designed Neighborhood Commercial, Designed Recreation, and Designed Commercial Zones, for any use permitted by special permit or special exception, the Commission/Board may, as part of such special permit or special exception, permit a reduction in the minimum front yard of up to 50% of the required lot front yard distance where all parking, loading areas, and driveways parallel to the street are located in the side or rear yards.
C. 
All zones. See the requirements of Article 4, General Regulations, and specifically the requirements for buildable area contained in § 315-4.04.
